Here is my weekly weather quiz question for the last time. What is a “Theodolite “? Here is the correct answer. A Theodolite is an instrument used in surveying to measure horizontal and vertical angles with a small telescope that can move in the horizontal and vertical planes. It used to track the movements of either a ceiling balloon or a radiosonde.
